Question

A rectangular block is 16cm long, 12cm broad and 5cm high. find its total surface area and volume​

Answer 1

Answer:

volume is l×b×h.

thats 16*12*5 that is 960cm cubed.

total surface area is 2(l×b+b×h+h×l).

that's 2(16×12+12×5+16×5).

664 cm squared .

Answer 2

Answer:

surface area=2(lb+bh+hl)

surface area=2(16×12+12×5+5×16)

surface area=664cm²

volume = 16cm×12cm×5cm

volume= 960cm³
